Thats basically my point, replace the desktop and external stuff with a small laptop that can fit in a bob. Mine fits in an 8.5"x11"x1" case that looks like a paper planner and easily slides down in the backpack that is my bob. I forsee the real need to bug out being more of a NOLA situation rather than the end of the world. Those situations your going to be bugging out to a hotel short term or an apartment long term and you may need to get up an running fast and won't have anything to plug just a drive in to. For that matter I wouldn't plug a drive on mine into anyone elses computer anyway, never know what you might pick up as there are so much virus and other malware out there. They you need to have all the software installs available. But with a laptop you just need power, plug in at the hotel and boot up no trying to find/borrow/buy another computer to plug a drive in to.
